Abstract

In general, the value of Newton's gravitational constant big G has one of the longest history of measurements in physics, but a definite value is still not in sight. Surprisingly, in spite of the fundamental importance of the Newton's universal gravitational constant big G, the more the precision of measurements of Newton's constant big G increased, the more the disparity of the measured value of Newton's constant big G increased. Different groups of experimentalists are repeatedly obtaining conflicting results for the exact value of Newton's constant big G. Is this high degree of uncertainty of Newton's constant big G a result of experimental errors or is the same at the end not a constant at all? The purpose of this publication is to refute the constancy of Newton's constant big G by the proof that Newton's gravitational constant big G is not a constant.
